Lab 1a

Good afternoon, I was working on my max labs 1 and 2 trying to redo them both but I kept getting errors which stopped me from being able to create the pitch tab and files saying I already completed this. When I grade my max lab 1 it is a zero even though I can't follow the direction of the assignment because of this error. So I can't fix what is wrong resulting in a zero on the assignment. Thank you for your time below is the error message.
